Search for top-squark pairs decaying into Higgs or Z bosons in pp collisions at √s=8 TeV
A search for supersymmetry through the direct pair production of top squarks, with Higgs (H) or Z bosons in the decay chain, is performed using a data sample of proton-proton collisions at s=8 TeV collected in 2012 with ...
Measurement of the production cross sections for a Z boson and one or more b jets in pp collisions at √s = 7 TeV
The production of a Z boson, decaying into two leptons and produced in association with one or more b jets, is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV. The data were ...
Identification techniques for highly boosted W bosons that decay into hadrons
In searches for new physics in the energy regime of the LHC, it is becoming increasingly important to distinguish single-jet objects that originate from the merging of the decay products of W bosons produced with high ...
